As The Crow Flies:

The expression as the crow flies is an idiom for the most direct path between two points, rather similar to "in a beeline". This meaning is attested from the early 19th century,[1][2] and appeared in Charles Dickens's 1838 novel Oliver Twist:

“We cut over the fields at the back with him between us – straight as the crow flies – through hedge and ditch.”

Honeymoon

Back in the day of arranged marriages , some young couples met for the first time at the altar. To help the marriage to be more successful to a couple who were complete strangers , they were made to drink a fairly large cup of mead (honey) every day for a month (moon).

So basically you had a good time with your new spouse being both of you were drunk for a month.

Loose as a Goose:

Completely relaxed. This phrase, probably aided in longevity by the rhyme, dates from the first half of the 1900s. In earlier usage it sometimes denoted promiscuity (loose morals), diarrhea (loose bowels), and so on, but since about 1950 it has mostly stuck to its present meaning. The Los Angeles Times (April 7, 1979) had it in this sense: “Philadelphia Phillies’ manager Danny Ozark is loose as a goose despite intense pressure to win.”
